Underground multi-system fusion scheme of coal mine safety monitoring and control system

For multi-system fusion requirement in Technology schemes of upgrading of coal mine safety monitoring and control system(exposure draft), existing multi-system fusion condition of coal mine was analyzed, and an underground multi-system fusion scheme in collection control layer was proposed as well as an underground fusion substation. The fusion substation can realize three fusion modes including substation fusion, link fusion and data fusion according to interfaces and communication protocols of field devices in multi systems. The test result shows the fusion substation can access safety monitoring and control system, personnel location system, mine pressure monitoring system, gas drainage monitoring system and so on at the same time for data sharing.
